General ESC and motor question

[D.O.G.]

I want to know if this esc and motor setup will work with my new foam plane. I have 2204/1700Kv with a 18a esc, instead of 12a esc and 8040 slow prop. for my Galaxy plane HobbyKing Galaxy High-Performance 3D Airplane w/ Motor (ARF). I want to know if I can use that 2204/1700Kv and 18a esc and 8040 slow prop. on my new Hummer plane. HobbyKing Galaxy High-Performance 3D Airplane w/ Motor (ARF) That plane calls for 2212/2213 with 1000Kv motor with a 20a esc and 1047 slow prop.

First... I think you meant to link to the Hummer and I think the following is that link..

H-King Hummer Xtreme 3D EPP Aerobatic Profile Plane (Kit) 1000mm (39.4

If you're after an RC Plane then HobbyKing stock a wide range. The H-King Hummer is an extreme 3D EPP profile plane to have you flying aerobatics in no time.

Opps. I fixed it Randy. Thanks

First thing... You'll need to know what the max amps for your 2204/1700Kv motor can handle... If that motor is made for a 2s pack, then going to a 3s pack will lower the amount of amps you can pull without overheating the motor.

Next... the recommended motor is for a 1000Kv motor ... a 1700Kv is more than 30% higher rpm. You'd fly a lot faster if using the same recommended prop... but you could go with a prop that has less pitch to help counter that, it'd also have an added benefit of lowering the amp draw as well.

Cool beans then. I'll get a different prop instead. What size do you recommend. You seen my other videos on what kind of flying I like to do. Fast isn't one.

First thing I'd worry about... is the max amps the motor you intend to use can pull ... If it can't handle both higher voltages and amps... it's a non-starter. If it can handle it... you have a throttle you can pull back on if needed... just don't use as much of it and test it out with a lower pitch prop if you have one to start with.

I'll point out something you probably already know, you are going from a 10" prop down to an 8" ... that also means it will be pulling less amps, so an upside there. You did drop the pitch slightly from a 47 to a 40 as well as the length... each of those will be about an 80% drop ( 80% of 80% of that 1700Kv ) ... The math seems to indicate it will be close but you won't know until you actually test fly it.

If the motor can handle the amps it will be pulling... you should be close to what you want... MAYBE ... lol

Well then, there's only one way to find out like you said. She's ready for a test flight then. I'll try to make Thursday mornings to fly. If life doesn't get in the way. If it doesn't work then I know to get a different set up LMAO
